A nurse is providing discharge teaching to a client diagnosed with Bell's palsy. Which instruction should the nurse include to prevent complications?

해설
Eye protection is the priority to prevent corneal injury from incomplete eyelid closure in Bell's palsy. Other options are either not specific to eye care (cold compresses, massage) or overly restrictive (avoiding all facial expressions).

심화 해설

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a patient with Bell's palsy. Bell's palsy is an acute, unilateral paralysis of the facial nerve (Cranial Nerve VII), which controls the muscles of facial expression. A critical complication arises from the inability to fully close the eyelid (Lagophthalmos) on the affected side, leading to corneal drying, irritation, and potential ulceration. Therefore, the primary nursing focus is on corneal protection.

Answer Rationale: Key Point! The correct answer is ② Use artificial tears and wear protective eyewear when outdoors. This directly addresses the core pathophysiological problem. Artificial tears (lubricating eye drops) provide moisture to the exposed cornea, and protective eyewear (like glasses or an eye patch at night) shields the eye from dust, wind, and injury, preventing corneal abrasion or ulcer.

Distractor Analysis:
• Watch out for confusion! Option ①: "Apply cold compresses..." While cold may be used in the acute phase to reduce inflammation, it is not the priority for preventing long-term complications. The question focuses on discharge teaching for complication prevention, making eye care the undisputed priority.
• Option ③: "Massage the paralyzed facial muscles vigorously..." Gentle facial massage may be recommended, but vigorous massage is contraindicated as it could cause muscle strain or injury. The instruction lacks specificity and safety.
• Option ④: "Avoid all facial expressions..." This is incorrect and potentially harmful. Gentle facial exercises are often encouraged to maintain muscle tone and prevent atrophy. Complete avoidance is not therapeutic and can negatively impact the patient's psychological well-being and recovery.

Related Concepts: The nursing management of Bell's palsy also includes medication administration (e.g., corticosteroids like prednisone to reduce nerve inflammation, antiviral drugs), pain management, nutritional support (difficulty chewing), and emotional support due to the sudden change in appearance.
Concept Summary • Pathophysiology: Unilateral inflammation/compression of Cranial Nerve VII → paralysis of ipsilateral facial muscles.
• Key Complication: Incomplete eyelid closure (Lagophthalmos) → corneal exposure, drying, risk of ulceration.
• Priority Nursing Intervention: Protect the cornea (artificial tears, eye protection, possible taping of eyelid shut at night).
• Medication: Corticosteroids (reduce inflammation), antivirals (if viral etiology suspected).
• Recovery: Often spontaneous within 3-6 weeks; full recovery is common.

ConditionAffected NerveKey Clinical FeaturePriority Nursing Care
Bell's PalsyFacial Nerve (CN VII)Unilateral facial droop, inability to close eye, loss of taste on anterior 2/3 of tongueEye protection to prevent corneal injury
Stroke (CVA) affecting facial musclesUpper motor neurons (Corticobulbar tract)Facial droop typically spares the forehead (can raise eyebrows) due to bilateral innervationAirway protection & swallowing assessment (dysphagia), neurological monitoring

Anatomy, Physiology & Pharmacology Points • Cranial Nerve VII (Facial Nerve): Motor function for facial expression, taste for anterior 2/3 of tongue, parasympathetic secretion for lacrimal and salivary glands.
• Lagophthalmos: Inability to close eyelids completely. The corneal blink reflex is impaired, leading to loss of protective lubrication and cleaning.
• Prednisone (corticosteroid): Reduces inflammation and edema around the nerve, potentially improving recovery outcomes. Must be tapered; monitor for side effects (hyperglycemia, mood changes, GI upset).
Memory Tips • Acronym: BELL = Blink (can't), Eye (protect it), Lubricate (tears), Look (for improvement).
• Think: "Face the problem, protect the eye." The most visible symptom is on the face, but the most dangerous problem is for the eye.
High-Frequency NCLEX Topics Bell's palsy is a classic NCLEX topic. The exam consistently tests the priority intervention: eye care. You may also see questions on medication administration (timing of steroids), differentiating Bell's palsy from a stroke (forehead sparing), or patient education points (gentle facial exercises, use of straw for drinking).
Watch Out for Question Variations! • Instead of discharge teaching, the question could ask: "Which finding requires immediate intervention?" Answer: "Complaint of eye pain or gritty sensation" (indicating possible corneal abrasion).
• It could be a priority question: "What is the nurse's first action upon assessing a new patient with Bell's palsy?" Answer: Assess the eye for closure and corneal integrity.
• It could shift to medication: "The nurse is teaching a client prescribed prednisone. Which statement indicates understanding?" Correct response would relate to tapering the dose, not stopping abruptly.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse caring for Mr. Johnson, a 45-year-old who presented to the clinic with sudden onset of right-sided facial droop and inability to close his right eye. He is diagnosed with Bell's palsy and is being discharged with a prescription for prednisone and instructions for self-care.

Nursing Intervention Strategy:
1. Assessment: Perform a thorough neurological assessment focusing on cranial nerve VII. Use a penlight to check corneal reflex and assess for lagophthalmos. Ask about eye pain, dryness, or blurred vision. Assess ability to eat, drink, and articulate words clearly.
2. Nursing Care & Patient Education:
• Eye Care: Teach and demonstrate application of preservative-free artificial tears every 1-2 hours while awake. Instruct to wear sunglasses or protective glasses outdoors. Teach how to tape the eyelid gently closed at night using paper tape, applying from the cheekbone to the eyebrow to avoid putting pressure on the cornea.
• Medication: Emphasize the importance of taking prednisone exactly as prescribed (often a tapering dose) and not stopping abruptly. Discuss potential side effects (increased appetite, insomnia, mood swings).
• Facial Care: Recommend gentle facial massage from the chin upward to promote circulation, not vigorous rubbing. Encourage gentle facial exercises like smiling, frowning, and puffing cheeks in front of a mirror.
• Nutrition & Communication: Suggest eating soft foods, chewing on the unaffected side, and using a straw for liquids. Be patient with speech and provide emotional support, as the change in appearance can be distressing.
3. Patient Safety and Precautions:
• Contraindication: Do not use viscous ointments in the eye during the day unless specifically instructed, as they can blur vision. Nighttime ointments may be prescribed.
• Monitoring: The patient must return immediately if they experience severe eye pain, sudden vision changes, or signs of infection (redness, purulent discharge).

Nursing Procedure & Medication Flow Eye Protection Procedure:
1. Wash hands.
2. Have patient look up.
3. Instill 1-2 drops of artificial tears into the lower conjunctival sac of the affected eye.
4. If taping for sleep: Cut a piece of paper tape. Have patient gently close the eye as much as possible. Apply tape horizontally from the mid-cheekbone to just below the eyebrow, ensuring the eyelid is fully closed but without pulling the skin tightly.

Prednisone Administration:
• Action: Potent anti-inflammatory and immunosuppressant.
• Key Patient Teaching: Take with food to avoid GI upset. Report signs of infection (corticosteroids mask inflammation), black/tarry stools, or significant mood changes. Do not receive live vaccines while on therapy.
• NCLEX Alert: Abrupt cessation can cause adrenal insufficiency (weakness, fatigue, hypotension).
A Word from Your Senior Nurse "Bell's palsy can be frightening for patients—they look in the mirror and see a face that doesn't feel like their own. Our job is twofold: protect their physical health (starting with those vulnerable eyes!) and support their emotional well-being. In clinical practice, I've seen corneal ulcers develop in just a day or two from neglect. Your teaching on eye drops and taping is not just a discharge instruction; it's a critical prevention strategy. On the NCLEX, they love to test your ability to identify the most important problem. With Bell's palsy, never forget: the eye is the prize. Protect it first, and you've done your number one job."

  • Artificial Tears — Lubricating eye drops used to moisten and protect the cornea when natural tear production or distribution is inadequate.
